Description

【発明の詳細な説明】 本発明は電磁クラッチの改良に関するものである。[Detailed description of the invention] The present invention relates to improvements in electromagnetic clutches.

まず従来の電磁クラッチにりいて第１図、第２図によっ
て説明する。First, a conventional electromagnetic clutch will be explained with reference to FIGS. 1 and 2.

この電磁クラッチにおいては入力軸１力■転してもフィ
ールドコア部２に規格電流が通電されない状態ではアー
マチュア部３は入力軸１には拘束されないフリーの状態
にある。In this electromagnetic clutch, even if the input shaft is rotated by one force, the armature portion 3 is in a free state in which it is not restrained by the input shaft 1 when no standard current is applied to the field core portion 2.

即ち、入力軸１と軸受４は滑合されており、この軸受４
にアーマチュアハブ５が圧入嵌合され、さらにこのアー
マチュアハブ５にスプロケット６がねじ止めされている
。That is, the input shaft 1 and the bearing 4 are slidingly fitted together, and this bearing 4
An armature hub 5 is press-fitted into the armature hub 5, and a sprocket 6 is screwed to the armature hub 5.

アーマチュアハブ５とアーマチュア３との関係はアーマ

ノ・ブ５にリベット止めされた３本のレリーズスプリン
グ７によって連結され、そのレリーズスプリング７によ
ってアーマチェアノ１ブＳＯＵに偏寄させられている。The relationship between the armature hub 5 and the armature 3 is connected by three release springs 7, one end of which is riveted to the armature 3 and the other end to the armature knob 5. It is biased toward

そして、アーマチュア３の他面ばロータ８とある規定値
の間隔で円周上均一でなければならない。The other surface of the armature 3 and the rotor 8 must be spaced uniformly on the circumference by a certain specified value.

また、ロータ８のアーマチュア３と対向する面には摩擦
板９が設けられており、連結の確実性を増している。Furthermore, a friction plate 9 is provided on the surface of the rotor 8 facing the armature 3, increasing the reliability of the connection.

そして円周上の均一性を保障するためにはアーマチュア
３の端面ば軸受４の内径中心に対して厳しく直角度を得
てなげればならない。In order to ensure uniformity on the circumference, the end face of the armature 3 must be perfectly perpendicular to the center of the inner diameter of the bearing 4.

そして、そのように直角度を得るためには軸受４、アー
マチュア・・ブ５、リベットが正確に作られ、精密に組
合わされねばならない。In order to obtain such a perpendicularity, the bearing 4, the armature 5, and the rivet must be made accurately and assembled precisely.

本発明は以上のような難点を解決除去するもので以下第
３図、第４図に従って詳細に説明する。The present invention solves and eliminates the above-mentioned difficulties, and will be described in detail below with reference to FIGS. 3 and 4.

即ち、第３図のように軸受１０、アーマチュアハブ１１
．リベット及びスプロケット１２を一体成形に構成し、
この一体構成体Ａとロータ１３とを電磁的に結合させる
ことによって電磁クラッチの目的を達成するものである
。That is, as shown in FIG. 3, a bearing 10, an armature hub 11
．． The rivet and sprocket 12 are integrally formed,
By electromagnetically coupling this integrated structure A and the rotor 13, the purpose of the electromagnetic clutch is achieved.

また、一体構成体Ａのアーマチュア３に面する側に突起
１４が設げられており、これがアーマチュア３の位置及
び面振れ精度を保持する役目をはたすものである。Further, a protrusion 14 is provided on the side of the integral structure A facing the armature 3, and this serves to maintain the position and surface runout accuracy of the armature 3.

さらに本実施例では一体構成体Ａは鉄系オイルメタルで
作られており、内径軸受部はその組成密度が粗に含油す
る様に作られ、外周のスプロケット歯形部は密度が密に
作られ機械的強度が犬になる様に構成されている。Furthermore, in this embodiment, the integral structure A is made of iron-based oil metal, and the inner diameter bearing part is made so that its composition density is coarse and oil-retaining, and the outer circumferential sprocket tooth profile part is made densely packed and machined. It is structured so that the target strength is a dog.

以上説明したように本発明の構成によれば、軸受けに一
体形成された突起部が直接アーマチュア面を保持できる
ので、その直角度がきわめて高く保証されるものである
。As explained above, according to the configuration of the present invention, the protrusion integrally formed on the bearing can directly hold the armature surface, so that its perpendicularity is guaranteed to be extremely high.

【図面の簡単な説明】[Brief explanation of the drawing]

第１図、第２図は従来例を示す断面図、第３図は本発明
の要部を示した断面図、第４図は本発明の電磁クラッチ
の断面図である。 Ａは一体構成体、３はアーマチュア、１０は軸受、１１
はアーマチュアハフ、１２はスプロケット、１３はロー
ター １４は突起である。1 and 2 are cross-sectional views showing a conventional example, FIG. 3 is a cross-sectional view showing essential parts of the present invention, and FIG. 4 is a cross-sectional view of the electromagnetic clutch of the present invention. A is an integrated structure, 3 is an armature, 10 is a bearing, 11
